Patent DE-3405114-A1 (DE)
Title: Circuit arrangement for impedance matching
IPC: H03H11/28
Filed: 1984-02-14
Abstract: A circuit arrangement is proposed which is used for impedance matching between a heating conductor arrangement (10) also used as antenna and an input of an antenna amplifier for the signals of the long-oblique medium-oblique short-wave broadcast band. A first collective conductor (12) of the heating conductor arrangement is connected via a capacitor (23) to an input of a step-up transformer (25). The output of the transformer is connected to an impedance converter (30) of an antenna amplifier (29) for the long-oblique medium-oblique short-wave signals. The FM signals are picked up at the second collective conductor (13) of the heating conductor arrangement and supplied, unamplified as a rule, together with the amplified long-oblique medium-oblique short-wave signals to a radio frequency receiver. <IMAGE>

Title: Steam engine cycle with feedback of the waste heat by means of a multistage heat pump process, in particular for steam power stations (superheated and cold steam)
Inventor: GENSWEIN ALFONS DIPL ING
IPC: F24D10/00
Filed: 1984-04-06
Abstract: According to the invention, a steam engine cycle is specified by means of which a complete conversion of heat into mechanical work is theoretically possible, so that the known "CARNOT thermal efficiency" for heat engines is surpassed. In accordance with the working principle, the heat of condensation is transferred in steps from the condenser of the engine cycle (= Clausius-Rankine process or condensation process) by means of a separate, multistage and energy-saving heat pump process to the already deposited condensate in the liquid high-pressure cycle (downstream of the feed pump). The heat of condensation q0, including the heat pump work WWP is thus fed back regeneratively into the boiler (in superheated-steam power stations) or evaporator (in cold-steam power stations). The heat Qzu that is still to be fed from outside to the boiler or evaporator up to the full capacity thereof is thus a differential heat; it corresponds to the differential work Wab resulting from the turbine work WT or turbine heat QT and the compression work WWP of the heat pump. This results in the theoretical thermal efficiency for the entire thermal power station always being 100% for any thermodynamic temperature gradient present at the turbine (expansion engine) and in any temperature range used of the available primary heat source: With the steam engine cycle specified, it is possible ...

Title: Vibration damper for vehicles
Inventor: SAFTIEN UDO DIPL ING
IPC: F16F9/348
Filed: 1985-01-31
Abstract: A vibration damper for vehicles is described, the damper curve of which is to vary as a function of the load in order to adjust the ride comfort and driving safety according to the given speed of travel. To this end, the invention proceeds from a vibration damper in which a support element arranged on the piston rod of the damper piston bears on a spring washer of the valve closing element of at least one of the damping valves arranged in the damper piston. The damper piston is arranged axially adjustably on the piston rod in the direction of the support element designed as an accumulator. According to the effective pressure of the damping fluid in the vibration damper, which is produced by the relative rate of motion between piston rod and cylinder, the damper piston moves relative to the piston rod counter to its direction of movement. At the same time the accumulator, advantageously formed by a disc spring, is preloaded and the spring washer of the valve closing element correspondingly hardened. The flow resistance of this damping valve is consequently increased by a corresponding degree.

Title: Centring method for aligning windows adhesively bonded into a window frame and device for implementing the method
Inventor: SCHMID DIETER DIPL ING
IPC: E04F21/28
Filed: 1985-07-27
Abstract: The invention relates to a centring method for aligning windows which are adhesively bonded into a window frame and which are displaceable in the window plane until the adhesive sets, and a device for implementing the centring method. Before the centring process, the upper window edge of the window adhesively bonded in is aligned parallel to the upper frame profile of the window frame and the window is supported in this aligned position in a pressure-resistant manner with the lower window edge on the opposite frame profile of the window frame. Subsequently, the spreading-leg pairs are introduced, by two centring grippers of a centring device, which are coupled to one another synchronously in terms of pivoting angle, at approximately the same height into a gap between the side edges of the window and the associated frame uprights and the centring grippers are spread by means of a central actuating drive, the window being displaced into a central installation position. After this centring process, the actuating force of the actuating drive is stopped so that the centring device can be removed for renewed use.

IPC: A47C21/06
Filed: 1985-11-22
Abstract: The sub-mattress is intended to have an electrically conductive insert for screening electromagnetic radiation, by means of which insert a specific microwave spectrum of electromagnetic rays can effectively be screened. The electrically conductive insert consists of a multiplicity of waveguides which are arranged side-by-side and whose axial attenuation is dimensioned such that the electromagnetic radiation entering from the one side is damped in the waveguide such that it no longer emerges on the other side. In consequence, the electrically conductive insert is microwave-proof while nevertheless ensuring good transportation of air and moisture.

Title: Method and device for error compensation of the effect of the fundamental field
Inventor: MEUSSLING ECKHARD DIPL ING
IPC: G01D3/02
Filed: 1986-01-31
Abstract: The method and the device for error compensation of the effect of the fundamental field is applied in measuring the length of strand-shaped, axially moving material by means of magnet markings applied to the material. The aim of a higher accuracy and reliability in the measurement of length and the higher degree of automation thereby achievable in the measurement system is achieved by error compensation as a function of the signal on the material. The object is achieved according to the invention in such a way that two probes measure the distance between two zero-crossings of the magnet mark signal, and deviations in the distance are detected and these deviations are compensated by means of a changed setting of the working point of the probes. However, the compensation does not come into force until the signal of a further probe has reached a fixed threshold value. <IMAGE>

Filed: 1986-04-10
Abstract: The invention relates to a method and a device for determining the gripping position of automatic manipulators, and in particular for detecting the position and centreing parts that are to be gripped. The object of the invention is to provide a method which permits the direct measurement of the workpiece orientation and position or the distance between the workpiece and gripper during the gripping operation, in order therefrom to generate the control commands for the robot. This object is achieved in the method according to the invention by providing that the recording system, for example a semiconductor camera, is mounted in the hand root of the gripper in such a way that its visual (viewing) angle sweeps over the grip region and the orientation of the object to be gripped is determined with the aid of the recorded image. The distance between the workpiece and gripper is determined by mounting a laser in the hand root of the gripper, using the recording system to detect the light point projected onto the object by the laser, and evaluating the image produced.
